WOUND PACKAGE.

Application led July 3,

To all 'whom it may concern:

Be it known that I, SAMUEL A. BAnBoUR, a citizen of the United Statestresiding at Paterson, in the count-y of Passaic and State of New Jersey, have invented certain new and useful improvements in Wound fackages, of which the following is a specification.

This invention relates to wound shuttle packages of the class having a quill or the like elongated core for t e windings, and 1t has reference particularly to wound shuttle packages of this class in which the windings are composed of a filament siicli as tinsel, that is to say, material distinguishing from silk` cotton, wool and the like materials in that it is of considerably greater` weight; has a flat cross-section so that the windings lie in layers without interlock be tween the layers; is hard or unimpressionable, to such an extent in tact that even where th'e mass of windings represents many layers such mass is practically non-yielding to pressure; and is finally smooth, 1.*e., without any medium, such as the proJccting fibres in ordinary textile strands, acting to bind the components of the wound mass together.

Great 'difficulty hasbeen met with in the effort to utilize successfully wound pack ages of such material in shuttles for looms. The component coils having a tendency to expand and having no coupling of any kind with each other such as are afforded by the fibres in ordinary textile strands, and the material being hard and smooth and also fiatand oi uniform thickness so that the coils exist in theJ package as parts of distinct non-interlocking laminas from end to end of the mass, and the mass being in addition muchheavierthan a corresponding quantity of any other textile strands, as an incident oi the impelling and stopping of the shuttle at the ends of its flightA acrossthe lay more or less of the mass, usually at the free end of the package, slips away, with the result that the loom cannot be continued in operation for .many picks without a breaking down of the mass occurring and necessitating; the stopping ot the loom in order to remove the snarl of winding that results. These frequent stoppings are a great annoyance in weaving and they contribute very materially to increase in the cost of manufacture.

The object of this invention is toprovide 1922. Serial No. 572,513.

a wound package of the class indicated constructed so as to overcome this difficulty. The package illustrated in the accompanying drawing accomplishes this purpose, havo0 ing in considerable actual practice demonstrated that the necessity for stopping the loom on account of slippage of the .convolutions .thereof is substantially no more likely to occur with such a package than it 65 quill or Fig. 3 is an enlarged transverse sectional 75 view thereof on line 3 3, Fig..2, where the lwound mass is thickesti and Fig. 4l is a magnified longitudinal sectional view of the windings, this view being provided .in order to af'lord an idea of the cross 59 sectional form ot the material (tinsel) andl hou7 its coils exist in the package in distinct non-interlocking laminae.

The ordinary wound package employed in shuttles has a quill or core the diameter 85 y or thickness of which, in a package of about the dimensions shown in the drawing, would be about one-third of the diameter of the package shown in Fig. 3. In other words, in ordinary wound packages the 9@ quills diameter or thickness represents the minor part of the diameter of the entire package. Each time a'. shuttle in a loom is impelled across the lay and comes to a stop at the end of its flight the inertia of the @e wound mass tends' to displace it longitudinally of the uill or core. In packages of fibrous material, which is soft, round in. cross section, more or less light, and fuzzy,

this tendency is not free to plroduce any te@ But w practical disadvantage. en the material has the' hereinbefore mentioned characteristics of tinsel (to wit, hardness and smoothness, appreciable weight, a dat and uniformly thin cross-section and the tendm5 ency to lie fiatand so form distinct laminas,

as shown by Fig. 4, where the convolutions of the tinsel are indicated at a) it is free to do so, to the extent, as indicated, 4of be ing both a great source of annoyance in M@ weaving and of. addiw9 considerably to the cest ont production. how according to my invention, instead of I:forming the quill and wound mass so that they are so proportioned that the former represents the minor part and the latter the major part of the diameter of the entire package I proportion them so that the Wound mass b has so little thickness that relatively to the thickness of the quill or core c it is but a comparatively thin shell thereon. In actual practice, the quill or core is made much thicker than is usually the case, the object of which is to obtain larger convolutions of the windings and so considerably postpone the exhaustion of the package and also to increase the radius of the convolutions so that, not being bent too sharply, they are not so disposed to expand and s0 relax their Grip on the core. But I do not Wish to be imited to the quill or core being so enlarged, since the essence of my invention and the factor principally responsible for slipping thereof, notwithstanding the layers are much freer to slip than in ordinary packages.

It will be understood that the package is wound by the Well-known so-called traverse-Wound method, i. e., by effecting reciprocation as between the quill or core and a guide for the tinsel, and also advanc ing one of them at the same time or at intervals, longitudinally of the axis of the core.

Having thus fully described my invention, what I claim as new and desire t0 secure by Letters Patent is l. A wound package including an elongated core and a traverse-Wound mass of windings of a hard, smooth, flat and uniormly thick filament thereon, said mass.

having a thickness so little in respect to that of the core as to be but a relatively thin shell thereon. v

2. A Wound package includin an elongated core and a traverse-Wonu mass of windings of a flat and uniformly thick metal filament thereon, said mass having a thickness so little in respect to that of the core as to be but a relatively thin shell thereon.

In testimony whereof I afiix my signature.
